lMPROVEMENT IN PAPER BOXES.

Specification forming part of Letters Patent No. 210,9 53, datedDecember 17, 1878 application filed August 5, 1878.

To all whom it may concern:

Be it known that we, JOSEPH P. BUGKING- HAM. of Ghicopee, in the countyof Hampden and State of Massachusetts, and OLIVER- M. HAMILTON, ofSpringfield, in the same county and State, have invented certain new anduseful Improvements in Paper Boxes, of which the following is aspecification Our invention consists of the peculiar form of lock forthe sides, the handle and manner of locking it in place, and thecombination of the handle and fastening-flap of the cover, all ashereinafter described.

In the accompanying drawing, Figure 1 is a plan view of abox whichembodies our invention, the same being represented as unfolded. Fig. 2is an end view of the same, represented as folded up and lockedtogether. Fig. 3 is a detached View of the same, showing the manner ofinserting the handle; and Fig. 4 is a side elevation of said box.

A designates the bottom of the box. B B B B designate the four sideswhich form the depth of the box; C O O O, the locking-straps, formed ontwo of saidsidcs, which are opposite each other, half of which strapshave shouldered tongues na, and half of which have eyes I) 1;, of theform shown in Fig. 1. The length of the eye transversely to said straps,and on the side nearest the part of the box to which the strap isconnected, is such that the body of the tongue a may be readily passedthrough it at that point, while the opposite side of said eye isnarrower in the same direction, and of the proper size to admit only theneck of the tongue just back of or between the shoulders.

D designates the top of the box, having end ilaps,c c,and side fiap,cl.The broken lines in Fig. 1 indicate the lines on which the parts arefolded in setting up the box.

Upon the side over which the side flap, cl, of the cover folds is ahandle, 7:, the ends of which are pointed and provided with shouldersin, as shown in Figs. 1 and 3. In this side of the box two straighttransverse slits are made, of a length a little greater than the widthof the handle just back of the shoulders m and extending from the endsof said straight slit at an angle thereto there are two curved slits, asshown in Figs. 1 and 3, said straight and curved slits being designated0 in the drawings.

By entering the point of the handle in the slit 0 when the handle liesflat against the side B, as shown in Fig. 3, it may be easily pushedthrough, thereby bringing the shoulders upon the insidcof the'box. Theother endis pushed through in like manner.

If the box is to be shipped in the fiat or knock-down form, the handlethus inserted may lie flat with the box, as shown in Fig. 1., By turningthe ends of the handle at right angles to the side of the box anddrawing the bulk of the handle through to the outside, the shoulders inwill engage the solid side of the box in line with the straight portionof the slit 0 and hold the handle in place.

The straps O O O O span two of the sides B B, and are locked together bypassing the tongues through the eyes, then dropping them a littlesidewise and letting them draw back into the position represented inFig. 2, the outlines of so much of the tongue as is back of other partsbeing indicated by broken lines,

By making the eye longer on one side than the other in a transversedirection, and correspondin g respectively to the width of the body andneck of the tongue, taken in the same direction, the latter can beinserted and locked in place without doubling over or bendingthe cornersor twisting the tongue.

Other styles of lockin g devicesas, for in stance, an ordinarybuckle-may be employed to secure the straps; and other material, such asleather or lec ther=board, may be employed to form a more substantialarticle for lunch boxes or other uses,

It is much more convenient to fill the box from one of its broadestsides, which we call the top of the box, and in order to leave the topaccessible for such purpose, we make the straps O O extend across theend from side to side, instead of from top to bottom.

The side flap, d, of the cover D is formed with a neck between thenotches n a, which will just fit in between the two ends of the handle hand fasten the cover in place, as shown in,

Fig. 4. If desired, the cover D might be omitted, or another coversubstituted for it, Without changing the other features of ourinvention. y

We are aware that boxes closed upon both top and bottom, and accessiblefor filling only at the ends, have been locked together at the ends byflaps connected to said top and bottom, or the two broadest sides of thebox; also,

that boxes have been made with short cornerflaps, which looked into oneof the four sides, but not into each other, and we hereby disclaim suchprior boxes.

We claim as our invention 1. In a knock-down box, the locking-straps C OO G,two of which have shouldered tongues an, and two of which areprovided with eyes b b, of a size at their inner sides corresponding ina transverse direction with the width of the tongues outside of theshoulders, and at their opposite and outer sides with the Width of theneck inside of said shoulders, substantially as described, and for thepurpose specified.

2. In a paper box, the handle shouldered at the ends, in combinationwith the side having slit 0, with straight and divergent portions,substantially as described, and for the purpose specified.

3. In a folding box, the handle projecting from one side, in combinationwith the cover D and its flap d, having notches n n, substantially asdescribed, and for the purpose specified.
